thank you gentlemen, this morning I flashed the SuperSu and it worked. Got my root access back and I was able to finish everything.
On top of that, I also used Titanium to restore some of the apps with data and everything went smoothly.
The only thing that I did differently was NOT to restore sms/mms (did not really care about having them) and I used a backup of my contacts as an vcf data file that exported before i wiped and flashed a new ROM.
So the phone works like a champ now, it had been restarting for a month without a cause.
